Besidka

Who I am

The hosted Besidka service at www.besidka.com is provided by Serhii Chernenko, an individual resident in Poland (European Union). Besidka is a personal, non-commercial project and not a registered business — there is no company, no sole proprietorship and no VAT registration behind it.

That one address handles everything — general questions, privacy requests, reports of illegal content, and enquiries from authorities. It is read by a person, not a bot, and it is the fastest way to reach me.

In these terms, "I" and "me" mean the person above, and "you" means the person using the service.

What these terms cover

These terms are an agreement between you and me about the hosted service at www.besidka.com.

They do not cover copies of Besidka that other people run. If you run your own copy, you set your own terms, you are the data controller for it, and under the EU AI Act you are the provider or deployer of that system. I have no access to and no responsibility for it.

By creating an account or using the service you accept these terms. If you do not accept them, please do not use the service.

The service

Besidka is a chat interface to third-party AI models. I provide the interface, the storage for your chats and files, and the plumbing that talks to the model.

I do not provide the AI model. You supply your own API key from an AI provider (currently OpenAI or Google AI Studio), and your prompts are sent to that provider using your key.

There is no payment

The hosted service is free. There is no subscription, no paid tier, no advertising, no donations and no payment processor. You never pay me anything and I never ask for card details.

You pay your AI provider directly for the model usage under your own account with them. Their pricing, invoices and limits are between you and them. I do not resell, mark up or take a share of it, and I am not a party to that contract.

Because you never pay me for anything, there is nothing to refund and no right of withdrawal from a purchase arises.

If that ever changes

The absence of any revenue is not an accident, and it is part of what these terms are built on. If I ever introduce advertising, sponsorship, donations (including a "buy me a coffee" style button to cover hosting), a paid tier, or any monetisation of user data, the service stops being a non-gainful personal project. I would then publish a full set of service-provider details, including a postal address, and update these terms before that change takes effect, with advance notice as described under Changes to these terms.

Who may use it

You must be at least 18 years old. Besidka only works if you bring your own AI provider API key, and the providers set their own minimum age for an API account — Google AI Studio requires you to be 18 or over. You cannot use Besidka without such an account, so 18 is the minimum here too. By using Besidka you confirm you are 18 or over.

Your account

Give a real email address you control. You need it to verify your account and to reset your password.
Keep your password and your session to yourself. You are responsible for activity under your account.
One person per account. Do not share an account.
Tell me at privacy@besidka.com if you think someone else has access to your account.

You can delete your account at any time from your settings. That deletes your account and its data — see the Privacy Policy for exactly what happens, including the 30-day backup window.

You need your own API key

You must have the right to use the API key you enter, and you must comply with your provider's own terms and usage policies. Breaking them is between you and them, but it can also mean Besidka stops working for you.
Your key is stored encrypted (see the Privacy Policy), but you should still treat entering a key anywhere as a decision with risk. Use a key scoped and limited to what you need, and rotate it if you have any doubt.
You are responsible for the usage costs your key incurs, including costs from long conversations, large attachments and deep research runs.
I cannot see, refund or cap your provider spending. Set spending limits in your provider account if you want a ceiling.

You are interacting with an AI system

You are using an AI system. The text, code, summaries, images and reports you see are generated by a machine-learning model, not written by a person and not checked by me.

Output can be wrong. Models state incorrect things confidently, and they invent facts, quotations, numbers, names, links and citations that look plausible. Verify anything that matters before you rely on it.
It is not professional advice. Nothing you get from Besidka is medical, legal, financial, tax, psychological or other professional advice. It is not a substitute for a qualified professional. In an emergency, contact your local emergency services, not a chat app.
Deep research reports can be wrong in a specific way. A deep research report may contain fabricated or misattributed citations — sources that do not exist, or real sources that do not say what the report claims. Open and read the sources yourself before citing them.
Output is not unique to you. Another user with a similar prompt may receive substantially the same answer.
Do not use output to make decisions about other people (hiring, credit, eligibility, discipline) without a human being who is competent to make that decision reviewing it.

What you may not do

Do not use Besidka to:

Break the law, or to produce, store or distribute illegal content, including child sexual abuse material, terrorist content, or content that infringes somebody else's copyright or trade marks.
Harass, threaten, defame, stalk or doxx anyone.
Produce malware, exploits, phishing pages or other material designed to break into systems or defraud people.
Present AI output as human-written where doing so deceives someone to their detriment, or impersonate a real person or organisation.
Attack the service — no scraping at scale, no brute forcing, no attempt to bypass rate limits or access other users' data, no probing for vulnerabilities beyond good-faith reporting to me.
Resell or wrap the hosted service as your own commercial product. You may self-host the code instead; that is what the licence is for.

Do not submit sensitive personal data

Do not submit special category personal data. That means data revealing health, political opinions, religious or philosophical beliefs, trade union membership, genetic or biometric data, sex life or sexual orientation, or data about criminal offences and convictions.

The reason is practical as well as legal: whatever you type is forwarded to a third-party AI provider under your own key, and on a free Google Gemini key that provider may keep it and let human reviewers read it. I cannot undo that.

I build no features that infer, classify, score or profile anybody from the content of chats, and I do not read your chats.

Other people's data

If you put someone else's personal data into a chat, you are responsible for having a lawful reason to do that. If you then publish that chat with a share link, you are responsible for that publication too — see below.

Your content

You keep all rights in what you write and upload. I claim no ownership of it.

To run the service, I need a narrow, limited permission from you. You grant me a non-exclusive, royalty-free licence, limited strictly to operating the service for you, to:

store your content and serve it back to you;
transmit your content to the AI provider you chose, using your key, so it can answer; and
render your content on a share page that you yourself created, for as long as that share is active.

That is the whole licence. It is not perpetual, not transferable and not for any other purpose. It ends for any given content when you delete that content or your account. I do not use your content to train models, to advertise, or to build any other product.

The AI provider's rights over what you send it come from your agreement with that provider, not from this licence.

Sharing a chat is optional, off by default, and you switch it on per chat. Before you do, be clear about what it means.

Anyone with the link can read the chat, without an account. An unlisted URL is not access control. Publish nothing you would not put on a public page.
Indexing by search engines is a separate switch. A share is not indexable unless you turn that on too.
You choose an expiry (1 hour, 1 day, 1 week, 1 month, 1 year, or never) and you can revoke a share at any time.
Per-share switches control whether files, message metadata and your name and avatar are visible. Tool calls are always stripped out.
If you leave branching on, a signed-in visitor can copy the shared conversation into their own account and carry on from it. Their copy is theirs; revoking your share does not delete it.

What you promise when you publish a chat

By turning a share on, you confirm that:

you have the right to publish everything in that chat, including any content the model produced from material you supplied; and
you have a lawful basis to publish any third party's personal data that appears in it, and you have considered whether you should be publishing it at all.

Revoking is not undoing

Revoking a share stops access through me immediately and deletes the share record. It cannot recall search-engine caches, web archives, screenshots, downloads, branch copies or anything that was scraped while the link was live. I take the reasonable steps in my control; I cannot promise a published chat becomes unseen.

Reporting illegal content

Anyone — user or not — can tell me about content on Besidka they believe is illegal. I host user content and treat myself as an online platform, because share links are public.

Send reports to privacy@besidka.com. There is no form to fill in, and the mailbox is read by a person — it is not a bot-only address.

For the purposes of the Digital Services Act, that same address is my published single point of contact:

for users, and for anyone else reporting content; and
for Member State authorities, the European Commission and the European Board for Digital Services.

I accept reports and communications in English or Polish.

What to put in a report

To let me act quickly, please include:

A clear explanation of why you believe the content is illegal.
The exact URL (or URLs) of the content. For a shared chat, that is the share link.
Your name and email address, unless the report concerns child sexual abuse material or certain other offences against a person, where you may report anonymously.
A statement, made in good faith, that the information in your report is accurate and complete.

What I do with a report

I confirm I received your report, review it, and decide without undue delay whether the content stays up, is removed or is disabled. I tell you the outcome and how you can challenge it in court. Decisions are made by a person, not automatically.

If your report concerns a crime involving a threat to someone's life or safety, I will inform the relevant authorities.

Please do not send reports you know to be false. Reports that are manifestly unfounded and repeated may be ignored.

Statement of reasons

If I remove or disable your content, restrict its visibility, suspend a share link, or suspend or terminate your account, I will send you a statement of reasons. It will say what I did and to which content, why I did it — the legal ground or the rule in these terms I relied on — the facts I relied on, whether automated means were used, and how you can challenge the decision, including in court.

I will not send it where the law forbids it, or where I have no way to contact you.

I am a micro-enterprise and am therefore exempt from the Digital Services Act's transparency reporting and internal complaint-handling system requirements. I do not operate a formal internal appeals procedure — if you disagree with a decision, reply to the statement of reasons and a person will look at it again, and your right to go to court is unaffected.

Content moderation

I do not read your private chats and I do not run automated scanning of chat content. There is no system that flags or classifies what you write.

Moderation is therefore reactive. I act on reports, on notices from authorities, and on things I notice while running the service. When I act, I may remove or disable specific content, revoke a share link, restrict a feature for an account, or suspend or terminate an account for serious or repeated breaches of these terms. I aim to act proportionately, and I send a statement of reasons as described above.

Availability and changes to the service

There is no uptime guarantee. This is a free service run by one person. It may be slow, unavailable, or interrupted for maintenance, and features may change or be removed.
The service depends on third parties (Cloudflare and your AI provider). If they have an outage or change their terms, Besidka is affected.
I may discontinue the free hosted service. If I do, I will give you notice in the app and a reasonable period to get your data out before it is deleted, and I will tell you where to find the source code so you can host it yourself.

Changes to these terms

If I change these terms in a way that matters to you, I will give you advance notice — in the app, or by email if the change is significant — and say when it takes effect. If you do not accept the new terms, you can stop using the service and delete your account before that date. Continuing to use the service after the change takes effect means you accept it.

Small corrections that do not affect your rights or obligations (typos, clarifications, updated contact details) take effect when published.

Open source, self-hosting and the Besidka name

Besidka's source code is published under the MIT licence. You are free to use, modify and self-host it on those terms.

Two things follow that people often get wrong:

The MIT licence covers the source code, not this hosted service. The MIT "AS IS" disclaimer applies to the code you obtain under that licence. It does not disclaim anything about the service at www.besidka.com. My disclaimers for the service are the ones set out below, and they are subject to the mandatory law described there.
The MIT licence does not license the "Besidka" name, logo or brand. You may run your own copy; please do not present it as being Besidka, or use the name or logo in a way that suggests I run it or endorse it.

If you self-host, you are the operator: your users' data is yours to protect, these terms do not apply to your deployment, and you must write your own.

Disclaimers

To the extent the law allows, the hosted service is provided as it is and as available, and I give no warranty that it will be uninterrupted, error-free, secure, or fit for a particular purpose, and no warranty about the accuracy, completeness or usefulness of AI output.

Nothing in this section excludes or limits anything that cannot lawfully be excluded or limited, and it does not take away any statutory right you have that applies to you regardless of what these terms say.

Liability

I limit my liability only as far as the law allows — and no further.

I am always fully liable, without any limit, for:

harm I cause intentionally;
harm I cause by gross negligence;
death or personal injury; and
anything else where the law does not permit liability to be limited or excluded.

Polish law is explicit on the first of these: under Art. 473 § 2 of the Civil Code (Kodeks cywilny), any provision purporting to exclude liability for damage caused intentionally is void. So that provision does not exist here.

Subject to the above, and to the extent the law allows, I am not liable for:

loss or corruption of data, beyond restoring from my routine backups;
decisions you take, or content you publish, based on AI output;
what your AI provider does with your prompts, or what it charges your account;
unavailability of the service or of a third party it depends on; or
consequences of a share link you created, once the content has been public.

Nothing in these terms limits or excludes any right or remedy that cannot lawfully be limited or excluded. If a court finds any limitation here unenforceable, it is reduced to what is enforceable and the rest stands.

Governing law and where to go to court

These terms are governed by Polish law.

That choice of law is not a way to strip protections from you. To the extent the consumer rules apply to you as someone habitually resident in another EU or EEA country, Art. 6(2) of the Rome I Regulation applies: choosing Polish law cannot deprive you of the protection of the mandatory rules of the country where you habitually live, and those rules apply where they are more favourable to you.

Wherever you live, you can raise a dispute with me in the courts of your own country, and I will not argue that you had to travel to Poland to do it.

I would much rather sort a problem out by email first. Write to privacy@besidka.com.
